Sometimes we need to add trigger in our mysql database of laravel . but we think how to create the trigger by using laravel migration because laravel not provide any special function as like insertTrigger and also something so it is a problem to create direclty, But laravel DB::unprepared() through we can also create trigger for database.

So now in following example we can see how to create migration and need to create a trigger code and how to write drop the trigger code, so let’s do it this way.

Create Migration:
php artisan make:migration add_trigger
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class AddTrigger extends Migration
    public function up()
        DB::unprepared('CREATE TRIGGER add_Item_city AFTER INSERT ON `items` FOR EACH ROW
                   INSERT INTO `items_city` (`item_id`) VALUES (;
    public function down()
        DB::unprepared('DROP TRIGGER `add_Item_city`');
